Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747620, here are decompositions:

  • 3 + 8747617 = 8747620
  • 17 + 8747603 = 8747620
  • 41 + 8747579 = 8747620
  • 47 + 8747573 = 8747620
  • 59 + 8747561 = 8747620
  • 107 + 8747513 = 8747620
  • 131 + 8747489 = 8747620
  • 137 + 8747483 = 8747620

Showing the first eight; more decompositions exist.
